Where this 5.5 kW SH3 fits on a machine
The Schneider Electric SH32051P02F1200 is a 205 mm flange, three-phase servo motor in the SH3 family sized for mid-range axis work — packaging lines, machine-tool feeders, and palletiser drives where 5.5 kW continuous output moves the load without oversizing the cabinet. The motor housing is IP67 with IP65 at the shaft bushing per IEC 60034-5, so the body tolerates wet environments while the shaft seal keeps oil and coolant off the bushing — adequate for a washdown-adjacent cell, though not a full food-grade jets-and-immersion zone. Cooling is natural convection, not a fan; that choice keeps acoustic noise and moving-parts failure modes off the axis but means continuous torque must be derated against the ambient temperature profile rather than treated as a steady-state figure.
Torque and speed across the supported voltage rails
Nominal speed is bus-voltage dependent: 3000 rpm at 400 V three phase and 3600 rpm at 480 V three phase, dropping to 1500 rpm at 230 V single phase and 750 rpm at 115 V single phase — so the drive sizing decision is really a bus-voltage decision before it is a power decision. Nominal output power tracks that same curve: 5500 W at 400 V three phase, 5200 W at 480 V three phase, 4240 W at 230 V single phase, and 2510 W at 115 V single phase. Nominal torque inverts that curve because power equals torque times speed: 17.5 N.m at 400 V three phase and 13.8 N.m at 480 V three phase, climbing to 27 N.m at 230 V single phase and 31.9 N.m at 115 V single phase — the lower the bus voltage, the more torque per amp at the cost of speed. Continuous stall torque is 36.9 N.m across the 115 to 480 V three-phase range, and peak stall torque reaches 110 N.m for short bursts — the 3x ratio between continuous and peak is what makes the axis accelerate aggressive inertial loads without tripping the drive. Maximum RMS current is 87.2 A, identical to the 3-second peak output current, so the drive's continuous and peak current limits can be set to the same value without under-utilising the motor's thermal envelope.
Holding brake and shaft-side load ratings
The motor ships with a holding brake rated at 80 N.m, which exceeds the 36.9 N.m continuous stall torque by a 2:1 safety margin — enough to hold a vertical axis against gravity in a stopped state without relying on drive regen. Shaft-side loads are bounded by 740 N axial and 3730 N radial at 1000 rpm (dropping to 2580 N radial at 3000 rpm), so a belt reducer or pinion that pushes radial load past the curve will wear the front bearing long before the windings give out. The smooth 38 mm shaft is 80 mm long, which gives a coupling or pinion enough engagement to handle the 110 N.m peak torque without keyway fretting on direct-coupled axes.
Mounting geometry and electrical interface
Mounting is international-standard flange with a 205 mm flange, 180 mm centring collar at 4 mm depth, and four 14 mm mounting holes — the panel-builder must reserve that bolt circle on the gearbox or machine face before committing the BOM line. Length is 370.5 mm motor body, which sets the cantilever moment when the axis is mounted on a cantilevered gearbox; check the gearbox input-shaft length so the motor face seats flush without preloading the bearings. Electrical connection is a straight connector rather than a flying lead, so the cable gland and shield termination live on the connector backshell — order the matching shielded power and resolver/Hiperface cables from the same drive family to keep the EMC and grounding story clean. The five-pole stator with a 104 V/krpm back-EMF constant at 20 °C and 1.75 N.m/A torque constant at 120 °C gives the drive commissioning engineer a clean way to back-calculate flux and torque scaling during autotune.
Sourcing posture and what to ask for at RFQ
The listing carries no formal production-status flag beyond current stock notation, so lifecycle should be reconfirmed at quote time — for a SH3 motor of this size, the practical question is whether the gearbox mating half, Hiperface cable, and drive from the same family are still being shipped alongside it.
